Developing high-performance and reusable adhesives from renewable feedstocks is of significance to sustainable development, yet it still remains a formidable task. Herein, castor oil, melevodopa, iron ions are used as building blocks construct novel bio-based supramolecular adhesive (BSA) with outstanding adhesion performances. It prepared through partial coordination between melevodopa functionalized oil Fe3+ ions. Noncovalent interactions adherends the catechol unit contribute reinforcing adhesion, metal-ligand utilized strengthen cohesion. By combining strong tough cohesion, BSA achieves an strength 14.6 MPa at ambient temperature, record-high value among reported well best knowledge. also outperforms those cryogenic realizing another 9.5 -196 °C. In addition, displays excellent multi-reusability more than 87% original remaining even after reuse for ten times. highly anticipated that this line research will provide new insight into designing performances multi-reusability.

Abstract Sustainable adhesives with simultaneous high strength and excellent ductility are important but still challenging. Here, an epoxy adhesive simultaneously strong, tough, sustainable features by designing a new hierarchical energy‐dissipated cross‐linking structure is reported: annular containing quadruple internal B─N coordination boronic esters (AQBN). Under small strain, the AQBN rigid to enhance tensile of adhesive. With medium strain applied, its non‐coplanar ring can orderly open, providing mechanical energy dissipation ductility. Therefore, this multilevel endow both toughness. Besides, rapid dynamic exchange in enable have good sustainability environmental tolerance, respectively. As result, exhibit (18.5 MPa), outstanding toughness (work debonding 29692 N m −1 ), chemical/physical recyclability, reliability (humidity, water, high/ultralow temperature, organic solvents). This work provides strategy for balancing strength, toughness, adhesives.

Abstract The development of multifunctional bio‐adhesive plays a critical role in achieving sustainable society, where the intrinsic sensitivity to water and poor dynamics severely bottlenecks its scale‐up application. Inspired by microstructure dragonfly wings, strong tough adhesive with excellent reprocessability is designed developed creating dynamic network consisting lignin polyurea (LPU) framework soybean protein (SP). LPU act as rigid nervures slow crack propagation transfer stress, while SP dissipate strain energy through interplay from graded hydrogen imine bonds generated between SP. achieves significant enhancements fracture toughness resistance ≈7 23 folds, respectively, compared Furthermore, capacity for diffusion restoration endows superior reprocessability, enabling recycled particleboard achieve high retention modules (over 80%). This approach offers promising eco‐friendly alternative conventional petrochemical adhesive.

Abstract The resistance of adhesives to organic solvents is paramount importance in diverse industries. Unfortunately, many currently available exhibit either weak intermolecular chain interactions, resulting insufficient solvents, or possess a permanent covalent crosslinked network, impeding recyclability. This study introduces an innovative approach address this challenge by formulating zwitterionic poly(ionic liquid) (ZPIL) derivatives with robust dipole–dipole incorporating sulfonic anions and imidazolium cations. Due its unique dynamic electrostatic self‐crosslinking structure, the ZPIL exhibits significant adhesion various substrates demonstrates excellent recyclability even after multiple tests. Significantly, exceptional stability across nonpolar polar including ionic liquids, distinguishing itself from nonionic polymers conventional liquid)s. Its adhesive performance remains minimally affected prolonged exposure soaking conditions. presents promising solution for design highly solvent‐resistant materials plastics, coatings, adhesives.
